Safety/pressure maintenance valve in vertical installation position

The discharge or holding pressure of the safety/pressure maintenance valve can be infinitely adjusted between 1.5 - 12 bar via the control valve. Excessive mains pressure is relieved by quickly opening the main valve. To avoid pressure shocks, the closing speed is adjustable via the throttle check valve.

Usage:
- Safety valve for vertical installation position
- Flow direction from bottom to top
- Protection of a network against overpressure (safety valve)
- Maintaining the set mains pressure in the upstream pipe network (pressure maintenance valve)

Minimum inlet pressure: 1 bar
Minimum pressure difference between inlet and outlet pressure: 1 bar
For the dimensioning, we ask for the following information:
- Flow (max.)
- Inlet pressure (P1-sided)
- Holding pressure or release pressure (p1-sided)
- Holding pressure / back pressure (p2-sided)

Ingredients:
1: Main valve
2: Ball valve (A, B, C)
3: Filters
4: Aperture
5: Throttle Check Valve
6: Control valve
7: Pressure gauge with ball valve
8: Visual position indicator with drain screw (option: electric position indicator, opening limiter)
